What is microtrenching?
Microtrenching is a method used to install conduit by cutting a narrow, shallow trench — usually along the edge of an asphalt roadway.
Typical trench dimensions range from .75 in to 2.25 in wide (19.1 mm to 57.2 mm) and 8 in to 17 in deep (20.3 cm to 43.1 cm).
Mircrotrenching is widely used for deploying fiber-optic cables, telecommunications lines and low-voltage power utilities. It's especially popular in urban environments where minimizing surface disruption is critical.
During the cutting process, a vacuum system attached to the cutter wheel housing removes dry, dusty debris from the site, keeping the work area clean. After the conduit is placed in the trench, it is backfilled with a grout compound to secure it in place.
